Step-by-step explanation:
Answer:
![x = 9](https://tex.z-dn.net/?f=x%20%3D%209)
Step-by-step explanation:
Given
![WX = x + 5](https://tex.z-dn.net/?f=WX%20%3D%20x%20%2B%205)
![XY = 3x - 13,](https://tex.z-dn.net/?f=XY%20%3D%203x%20-%2013%2C)
Required
Find x
To do this, I will assume
.
So, we have:
![x + 5 = 3x - 13](https://tex.z-dn.net/?f=x%20%2B%205%20%3D%203x%20-%2013)
Collect Like Terms
![x - 3x = -5 - 13](https://tex.z-dn.net/?f=x%20-%203x%20%3D%20-5%20-%2013)
![-2x = -18](https://tex.z-dn.net/?f=-2x%20%3D%20-18)
Divide by -2
![x = 9](https://tex.z-dn.net/?f=x%20%3D%209)
Answer:
Growth rate = 8% = 0.08
Initial value (Po) = $255
F(t) = Po* e^rt
F(t) = $412.09897
Step-by-step explanation:
Given that:
Initial cost = $255
Rate of increase per year (r) = 8% = 0.08
Growth rate :
Final amount = Initial amount * (1 + rate)^time
Growth rate = 8% = 0.08
Initial value (Po) = $255
Exponential model for the cost :
F(t) = Initial value * e^(rate * time)
F(t) = Po* e^rt
Value after 6 years :
F(t) = Po* e^rt
t = 6
F(t) = 255 * e^(0.08*6)
F(t) = 255 * 1.6160744
F(t) = $412.09897
